The present invention relates to wireless communications, and in particular, to methods and user equipment (User Equipment, UE) for early evaluation termination.

In the traditional 3rd Generation Partnership Project (3GPP) 5G New Radio (NR) network, the time value or count value of the network configuration is introduced for some processes to prevent false alarms police. For example, a network-configured time value is introduced for the UE to trigger the measurement reporting process for the handover process, and another network-configured time value is introduced for the UE to declare a Radio Link Failure. RLF), which introduces a network-configured count value to the UE to trigger beam failure recovery or random access procedures.

However, the above time values and count values are configured by the network and remain unchanged until the UE receives the network reconfiguration. They cannot be dynamically adjusted by the UE, so a large amount of time may be wasted (i.e., the UE's evaluation delay). Make the UE wait for the corresponding process to be triggered or declared.

The present invention can provide a method and UE for early termination of evaluation. In particular, the UE can receive a downlink (Downlink, DL) reference signal (RS) from the network. The UE can measure the DL RS to obtain the measurement results. The UE may then adjust the time value or count value based on the measurement results. This time value is used by the network configuration to trigger the measurement reporting process or declare a radio link failure. This count value is configured by the network to trigger a beam failure recovery process or a random access process.

Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

Figure 1 may illustrate an exemplary 5G NR network 100 for early termination assessment in accordance with aspects of the present disclosure. The 5G NR network 100 may include a UE 110 communicatively connected to a licensed frequency band in an access network 120 ( For example, in a cell 121 operating in millimeter waves (30GHz to 300GHz), the access network 120 can use Radio Access Technology (RAT) (such as 5G NR technology) to provide radio access. The access network 120 can be connected to the 5G core network 130 through the NG interface. In particular, it can be connected to the user plane function (UPF) through the NG user-plane part (NG user-plane, NG-u). Connected to the Access and Mobility Management Function (AMF) through the NG control-plane (NG-c). A cell can be connected to multiple UPF/AMF to achieve load sharing and redundancy. The UE 110 can be a smartphone, a wearable device, an Internet of Things (IoT) device, a tablet, etc. Alternatively, the UE 110 may be a laptop or a personal computer (PC) with a data card inserted or installed to provide wireless communication functions, where the data card may include a modem and a radio frequency (Radio Frequency, RF) transceiver. device.

Cell 121 may provide communication coverage for a geographical coverage area, which may support communication with UE 110 through communication link 101 . The communication link 101 shown in the 5G NR network 100 may include uplink (UL) transmission from the UE 110 to the cell 121 (such as on the Physical Uplink Control Channel (PUCCH) or Transmission on the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH)) or DL transmission from the cell 121 to the UE 110 (such as on the physical downlink control channel (Physical Downlink Control Channel, PDCCH) or physical downlink sharing Channel (Physical Downlink Shared Channel, PDSCH))). Cell 121 may communicate with another cell (not shown) via an inter-cell communication link.

Figure 2 is a simplified block diagram of a cell 121 and a UE 110 according to an embodiment of the invention. For cell 121, antenna 197 can send and receive radio signals. The RF transceiver module 196 coupled to the antenna can receive the RF signal from the antenna, convert the RF signal into a baseband signal, and send the baseband signal to the processor 193 . The RF transceiver module 196 also converts the baseband signal received from the processor 193, converts the baseband signal into an RF signal, and sends it to the antenna 197. The processor 193 processes the received baseband signal and calls different functional modules and circuits to perform functions in the cell 121 . Storage medium 192 may store program instructions and data 190 to control the operation of cell 121.

Similarly, for UE 110, antenna 177 can transmit and receive RF signals. The RF transceiver module 176 coupled to the antenna can receive the RF signal from the antenna, convert the RF signal into a baseband signal, and send the baseband signal to the processor 173 . The RF transceiver module 176 can also convert the baseband signal received from the processor 173 into an RF signal and send it to the antenna 177 . The processor 173 may process the received baseband signal and invoke different functional modules and circuits to perform features in the UE 110 . Storage medium 172 may store program instructions and data 170 to control the operation of UE 110.

The cell 121 and the UE 110 may also include some functional modules and circuits, which may be implemented and configured to perform embodiments of the present invention. In the example of Figure 2, cell 121 may include a set of control functional modules and circuits 180. Evaluation circuitry 182 may handle early termination evaluation for certain processes and related network parameters for UE 110 . Configuration and control circuitry 181 may provide different parameters to configure and control the UE 110. UE 110 may include a set of control functional modules and circuitry 160. Evaluation circuitry 162 may handle early termination evaluation of some processes and related network parameters. Configuration and control circuitry 161 may process configuration and control parameters from cell 121.

Please note that the above different functional modules and circuits can be implemented and configured through software, firmware, hardware and any combination thereof. The above functional modules and circuits, when executed by the processors 193 and 173 (such as by executing the program codes 190 and 170), may allow the cell 121 and the UE 110 to perform embodiments of the present invention.

In some embodiments, UE 110 may receive network configuration (not shown) from a cell, such as cell 121 or another cell. The network configuration may include at least one of the following: (1) the first time value used to trigger the measurement reporting process (such as the time value of "timeToTrigger" according to the 3GPP technical specification); (2) used to declare the RLF The second time value (such as the time value of "T310" according to the 3GPP technical specification); and (3) the calculation used to trigger the beam failure recovery (Beam Failure Recovery, BFR) or random access (Random Access, RA) process Numeric value (such as the count value of "maximum number of beam failure instances (beamFailureInstanceMaxCount)" according to the 3GPP technical specification). Then, the UE 110 may be configured with at least one of the above-mentioned first time value, second time value and count value.

In different network processes, UE 110 can measure DL RS sent from cell 121 to obtain measurement results and adjust according to the measurement results: (1) first time value (can be used to trigger the measurement reporting process); (2) Second time value (can be used to declare RLF); or (3) count value (can be used to trigger BFR or RA processes). Accordingly, since the time value and count value used in different processes can be dynamically adjusted, a large amount of time wasted by the UE 110 waiting for triggering or declaring the corresponding process (ie, UE evaluation delay) can be prevented.

Figure 3 illustrates some embodiments of message transmission in accordance with novel aspects. In particular, cell 121 may be a serving cell serving UE 110, and the network configuration may include a first time value for measurement reporting (such as "timeToTrigger" according to 3GPP technical specifications).

In these embodiments, UE 110 may measure DL RS 1212 transmitted from cell 121 to derive measurements, and periodically update the measurements (ie, DL RS 1212 may be re-measured to derive updated measurements).

When a measurement result is measured or updated (i.e., when the UE 110 re-measures the DL RS 1212 to obtain an updated measurement), the UE 110 may compare the updated measurement result with at least one threshold, and based on the updated measurement result with the at least one threshold value Compare the results to determine a status. The UE 110 may then determine a scaling factor corresponding to the state and adjust the first time value based on the scaling factor.

UE 110 may then determine whether the event conditions are met. In particular, UE 110 may measure the signals of neighboring cells and determine whether any measurement results of the neighboring cells are larger than the measurement results of cell 121 by a specific margin. When the measurement result of a specific neighboring cell is greater than the measurement result of cell 121 by a certain magnitude (ie, when the event condition is met), UE 110 may start a measurement report timer for the specific neighboring cell.

The UE 110 may then continue to monitor the measurement reporting timer for that particular neighbor cell. When the measurement report timer of the specific neighboring cell reaches the adjusted first time value, the UE 110 may perform a measurement report procedure to transmit the measurement report to the cell 121 for the handover procedure.

It should be noted that in these embodiments, the measurement results may be measurement parameters of layer 1 filtering (L1-filtered) or layer 3 filtering (L3-filtered), where the measurement parameters may be reference signal received power (Reference Signal Received Power). , RSRP), Reference Signal Received Quality (RSRQ), Signal-to-Interference-plus-Noise Ratio (SINR), etc. At least one threshold may be preconfigured by network 100. The adjusted first time value may be used for all measurement report timers corresponding to the neighbor cell.

For example, the UE 110 may measure the DL RS 1212 from the cell 121 to obtain the measurement result "R1", and periodically update the measurement result "R1". When measuring or updating the measurement result "R1", the UE 110 may compare the measurement result "R1" with M1 thresholds and determine the state and the scaling factor corresponding to the state according to Table 1 below. condition Criterion Scaling factor (0≤K1 _i ≤1) 1 Threshold Threshold ₁ ≤R1 K1 ₁ 2 Threshold ₂ ≤R1＜Threshold ₁ K1 ₂ 3 Threshold ₃ ≤R1＜Threshold ₂ K1 ₃ … … … M1 Threshold _M1 ≤R1＜Threshold _M1-1 K1 _M1 Table 1

In this example, the measurement result "R1" can be determined to be between thresholds Threshold ₂ and Threshold ₃ . Therefore, the state can be determined as "3", and the corresponding scaling factor can be determined as "K1 ₃ ". Then, the time value "TTT1" of the measurement report's timeToTrigger can be adjusted by multiplying it by "K1 ₃ ".

UE 110 may then determine that the measurement result "R2" of neighboring cell "A" is greater than the measurement result "R1" of cell 121 by an amount "N", so UE 110 may start a measurement report timer for neighboring cell "A"" _TA ".

UE 110 may then continue to monitor the measurement report timer " _TA " for neighboring cell "A". When the measurement report timer " _TA " of neighboring cell "A" reaches the adjusted time value "TTT1", the UE 110 may trigger a measurement report to send the measurement report to the cell 121 for the handover process.

Figure 4 may illustrate some embodiments of message transmission in accordance with novel aspects. In particular, cell 121 may be a neighboring cell of UE 110, and the network configuration may include a first time value for measurement reporting (such as "timeToTrigger" according to 3GPP technical specifications).

In these embodiments, the UE 110 may measure the DL RS from the serving cell (not shown) to derive the measurements of the serving cell, and periodically update the measurements of the serving cell.

When the measurement results of the serving cell are updated (ie, when the UE 110 re-measures the DL RS transmitted from the serving cell to obtain updated measurement results), the UE 110 may determine whether the event condition is satisfied. In particular, when the measurements of the serving cell are updated, the UE 110 may measure the signals of the neighboring cells and determine whether there are any measurements of the neighboring cells that are greater than the measurements of the serving cell by a certain magnitude.

In these embodiments, UE 110 may measure DL RS 1214 transmitted from cell 121 (i.e., a neighboring cell) and determine that cell 121's measurements are larger than the serving cell's updated measurements by a certain magnitude (i.e., the event condition is satisfied ). Then, the UE 110 may compare the cell offset of the cell 121 with at least one threshold, and determine a state based on the comparison result of the cell offset of the cell 121 with the at least one threshold. Additionally, UE 110 may determine a scaling factor corresponding to the state and adjust the first time value based on the scaling factor.

UE 110 may then start a measurement report timer for cell 121 and continue to monitor the measurement report timer for cell 121. When the measurement report timer for the cell 121 reaches the adjusted first time value, the UE 110 may trigger the measurement report process to transmit the measurement report to the serving cell for the handover process.

It should be noted that in these embodiments, the measurement results may be L1 filtered or L3 filtered measurement parameters, where the measurement parameters may be RSRP, RSRQ, SINR, etc. At least one threshold may be pre-configured by network 100. The adjusted first time value may be used only for the measurement reporting timer of cell 121. It can also be said that each measurement report timer can correspond to an adjusted first time value.

Furthermore, the cell offset can be defined as:

Where O _cell,n is the cell offset of cell "n", Mn is the measurement result of cell "n", Ofn is the measurement object-specific offset of the reference signal of cell "n", Ocn is the cell of cell "n" Specific offset, Hys is the hysteresis parameter, Mp is the measurement result of the Special Cell (SpCell), Ofp is the specific offset of the measurement object of SpCell, Ocp is the specific offset of the SpCell cell, Off is the offset parameter.

For example, the UE 110 may measure the DL RS from the serving cell to obtain the measurement result "R3" of the serving cell, and periodically update the measurement result "R3" of the serving cell.

When the measurement result "R3" of the serving cell is updated, the UE 110 can measure the signal of the neighboring cell and determine that the measurement result "R4" of the cell 121 is greater than the measurement result "R3" of the serving cell by an amplitude "N".

The UE 110 may then compare the cell offset "Off1" of the cell 121 with M2 thresholds, and determine a state based on the comparison of the cell offset "Off1" of the cell 121 with the M2 thresholds. Additionally, UE 110 may determine a state and a scaling factor corresponding to the state according to Table 2 below. condition standard Scaling factor (0≤K2 _i ≤1) 1 Threshold Threshold ₁ ≤Off1 K2 ₁ 2 Threshold ₂ ≤Off1＜Threshold ₁ K2 ₂ 3 Threshold ₃ ≤Off1＜Threshold ₂ K2 ₃ … … … M2 Threshold _M2 ≤Off1＜Threshold _M2-1 K2 _M2 Table 2

In this example, it can be determined that the cell offset "Off1" is located between the thresholds Threshold ₁ and Threshold ₂ . Therefore, the state can be determined as "2" and the corresponding scaling factor can be determined as "K2 ₂ ". Then, the time value "TTT2" of the measurement report's timeToTrigger can be adjusted by multiplying it by "K2 ₂ ".

The UE 110 may then start the measurement report timer " _TB " for the cell 121 and continue to monitor the measurement report timer " _TB " for the cell 121. When the measurement report timer " _TB " for the cell 121 reaches the adjusted time value "TTT2", the UE 110 may trigger the measurement report process to transmit the measurement report to the serving cell for the handover process.

Figure 5 may illustrate some embodiments of message transmission in accordance with novel aspects. In particular, cell 121 may be a serving cell serving UE 110, and the network configuration may include a second time value for declaring RLF (such as "T310" according to 3GPP technical specifications).

In these embodiments, UE 110 may measure a set of Radio Link Monitoring-Reference Signals (RLM-RS) 1216 from cell 121 to derive measurements of estimated DL radio link quality, and Measurements of estimated DL radio link quality are updated periodically.

When the measurement results are derived (or updated), the UE 110 may determine an In-Sync (IS) indication or an Out-Of-Sync (OOS) indication based on the measurement results. UE 110 may then determine whether the RLF detection timer is running.

If so, UE 110 may compare the measurement result to the at least one threshold and determine a state based on the comparison of the measurement result to the at least one threshold. UE 110 may then determine the scaling factor corresponding to the state and adjust the second time value based on the scaling factor.

The UE 110 may then determine whether the UE 110 has received a consecutive number (such as "N311" according to the 3GPP technical specifications) of IS indications. If not, UE 110 may determine that the RLF detection timer reaches the adjusted second time value.

UE 110 may then continue to monitor the RLF detection timer of cell 121. When the RLF detection timer of cell 121 reaches the adjusted second time value, UE 110 may declare the RLF.

Please note that in these embodiments, the measurement results of the estimated DL radio link quality may be Block Error Rate (BLER), Signal-to-Noise Ratio (SNR), SINR, etc. At least one threshold may be preconfigured by network 100.

For example, the UE 110 may measure the RLM-RS 1216 from the cell 121 to obtain a measurement result "R5" of the estimated DL radio link quality, and periodically update the measurement result "R5". When the measurement result "R5" is obtained (or updated), the UE 110 may determine the IS indication or the OOS indication based on the measurement result "R5". The UE 110 may then determine that the RLF detection timer " _Tc " is running.

The UE 110 may then compare the measurement result "R5" with the M3 thresholds and determine the state and the scaling factor corresponding to the state according to Table 3 below. condition standard Scaling factor (0≤K3 _i ≤1) 1 Threshold Threshold ₁ ≤R5 K3 ₁ 2 Threshold ₂ ≤R5＜Threshold ₁ K3 ₂ 3 Threshold ₃ ≤R5＜Threshold ₂ K3 ₃ … … … M3 Threshold _M3 ≤R5＜Threshold _M3-1 K3 _M3 table 3

In this example, it can be determined that the updated measurement result "R5" is greater than the threshold Threshold ₁ . Therefore, the state can be determined to be "1", and the corresponding scaling factor can be determined to be "K3 ₁ ". Then, the time value "T3" of RLF's N310 can be adjusted by multiplying by "K3 ₁ ".

The UE 110 may then determine that the UE has not received "N311" consecutive IS indications and continue to monitor the RLF timer "T _c ". When the RLF timer " _Tc " reaches the adjusted time value "T3", the UE 110 may declare the RLF.

Figure 6 illustrates some embodiments of message transmission in accordance with novel aspects. In particular, the cell 121 may be a serving cell serving the UE 110, and the network configuration may include a count value for the BFR or RA process (such as "beamFailureInstanceMaxCount" according to the 3GPP technical specifications).

In these embodiments, the UE 110 may measure a set of beam failure detection RSs 1218 from the cell 121 to derive a measurement of the estimated DL radio link quality, and periodically update the measurement of the estimated DL radio link quality. .

When the measurement results are derived (or updated), the UE 110 may determine a beam failure instance indication based on the measurement results. The UE 110 may then determine whether a beam failure instance indication was received from the lower layer.

If so, UE 110 may compare the measurement result to the at least one threshold and determine a state based on the comparison of the measurement result to the at least one threshold. UE 110 may then determine the scaling factor corresponding to the state and adjust the count value based on the scaling factor.

The UE 110 may then increment a counter (such as "Beam Failure Instance Counter (BFI_COUNTER)" according to the 3GPP technical specification) by one. UE 110 may then continue to monitor the counter. When the counter reaches the adjusted count value, the UE 110 may trigger the BFR or RA process.

Note that in these embodiments, the measurements of estimated DL radio link quality may be BLER, SNR, SINR, etc. At least one threshold may be preconfigured by network 100.

For example, UE 110 may measure a set of beam failure detection RSs 1218 from cell 121 to derive a measurement result "R6" of the estimated DL radio link quality, and periodically update the measurement result "R6". When the measurement result "R6" is derived (or updated), the UE 110 may determine the beam failure instance indication based on the measurement result "R6" and determine that the beam failure instance indication is received from the lower layer.

The UE 110 may then compare the measurement result "R6" with the M4 thresholds and determine the state and the scaling factor corresponding to the state according to Table 4 below. condition standard Scaling factor (0≤K4 _i ≤1) 1 Threshold Threshold ₁ ≤R6 K4 ₁ 2 Threshold ₂ ≤R6＜Threshold ₁ K4 ₂ 3 Threshold ₃ ≤R6＜Threshold ₂ K4 ₃ … … … M4 Threshold _M3 ≤R6＜Threshold _M3-1 K4 _M4 Table 4

In this example, it can be determined that the updated measurement result "R6" is between the thresholds Threshold ₁ and Threshold ₂ . Therefore, the state can be determined as "2" and the corresponding scaling factor can be determined as "K4 ₂ ". Then, the count value "C1" of beamFailureInstanceMaxCount of BFR or RA can be adjusted by multiplying by "K4 ₂ ".

Then, the UE 110 may determine that the UE 110 increments the counter "BFI_COUNTER" by 1 and continues to monitor the counter "BFI_COUNTER". When the counter "BFI_COUNTER" reaches the adjusted count value "C1", the UE 110 may trigger the BFR or RA process.

The corresponding scaling factor. In step 905, the UE may adjust the time value used to trigger the measurement reporting process.

In step 906, the UE may determine whether a timer that triggers neighbor cell measurement reporting is running. If the result of step 906 is no, the method flow may proceed to step 907, the UE may start the timer for triggering the neighbor cell measurement report from zero, and then the method flow may proceed to step 904 to process the next qualified neighbor cell. .
